The Firepower 25 Sport (3548-09) is a 5.8 ounce, 900KV, 550 watt outrunner brushless motor capable of producing 70 oz of thrust from a 3 cell Lipo battery and a 13 inch prop. It will also provide very nice performance with a 4-cell Lipo battery.

The Firepower 25 Sport is roughly equivalent to .25 to .32 size glow engines. We installed the Firepower 25 Sport in a 40 size trainer, and used the APC 13x6.5E prop and two 11.1v 2200 30C Lipos connected in parallel with a Parallel Battery Harness. This combination provided a very good rate of climb and we could fly for over 20 minutes doing touch and go landings.

We recommend using a 50A to 80A Electronic Speed Control (ESC) with this motor.

We suggest using a 3 cell Lipo battery that is rated for about a 60 amp continuous discharge (or more), such as an 11.1v 2200 30C to 11.1v 4200 50C. Good 4 cell Lipo choices would be 14.8v 2200 50C to 14.8v 3300 50C.

The Firepower 25 Sport comes with 4.0mm connectors installed and 4.0mm female connectors and shrink tube are included.

MOUNTING OPTIONS: The Firepower 25 Sport can be mounted in front of a firewall using the 3500 series 'X' mount and the 3500 series rotor end prop adapter, which are included with the motor. You can also mount it behind a firewall, and a 5mm prop adapter can be purchased to mount a prop on the motor shaft.

Excellent Motor
Seems like excellent product. Came with wrong mounting screws but a call to Jess corrected quickly. Have mounted the motor and checked with watt meter and surprised by great results. As usual, Heads Up has super products at great prices and nextbto none service. Very fast delivery.

I have three of these in sport models and they run great. Nice and quiet with plenty of power.

Very good motor
I've put this motor on my Stik. It has plenty of power and I've NEVER had a problem with it. Great motor for the price.

needing a replacement motor for my Multiplex Extra 300 Weekender, I wrote to Heads Up help line, told them what I had and that I didn't have any idea what I needed. Help came back with some questions which I answered and they made the recommendation for the E-171 Firepower 25. It was a super recommendation and now the plane flies better than ever. Help was great and very responsive to my inquiry and I would recommend Heads Up to anybody and already have.
